FAQ

Commonly Asked Questions about VIQUA UV Systems and Parts

What VIQUA products does ESP Water carry?

ESP Water carries complete VIQUA point-of-use, whole-house, integrated, and commercial UV systems plus genuine lamps, sleeves, controllers, sensors, filters, valves, and service parts.

Which VIQUA system size should I choose?

Choose by the highest simultaneous flow the plumbing can deliver. A 12 GPM D4, 18 GPM VH410, or 30 GPM PRO30 is not selected by household size alone; pipe size, pressure, water quality, and the required UV dose or certification also matter.

What is the difference between standard and monitored VIQUA models?

Monitored models add a UV sensor and controller feedback about delivered performance. Standard models generally provide lamp status and replacement reminders without real-time UV intensity monitoring. Compare the exact feature list for the model.

Do VIQUA UV systems remove sediment, hardness, or dissolved minerals?

No. UV uses light to treat passing water; it does not physically filter sediment or reduce hardness and dissolved solids. Pretreatment may be needed to protect the quartz sleeve and keep water within the system specification.

How do I match a replacement lamp or sleeve to a VIQUA system?

Use the full model and replacement part number shown on the equipment label or manual. Match the Fits list on the product page; lamp length or connector appearance alone is not enough.

What routine maintenance should I expect with a VIQUA system?

Replace the lamp on its specified schedule, inspect and clean the quartz sleeve, replace damaged or hardened seals, service any prefilters, and verify controller, sensor, fan, or valve operation after maintenance.
